Webinar ZoomMtg.init works but ZoomMtg.join does not

We updated Web sdk to 1.9.9.
We can successfully init our webinar, but we can’t join it.
We have already applied solutions suggested in the topics regarding “cannot joining the meeting”, but without success.

ZoomMtg.checkSystemRequirements() returnes us following informations:

Zoom support you browser. Chrome/94.0.4606.71
You browser support below features {“browserInfo”:“Chrome/94.0.4606.71”,“browserName”:“Chrome”,“browserVersion”:“94.0.4606.71”,“features”:[“viewSharing”,“screenShare”,“computerVideo”,“computerAudio”,“callIn”,“callOut”,“chat”,“closedCaption”,“QA”,“POLLING”,“BREAKOUT”,“GALLARY”],“browserAbility”:{“SharedArrayBuffer”:false,“WebCodecs”:true}}

No error

Hey @it17 , happy to help!

Can you please clarify what you mean by does not work? Are the success or error callbacks being called?

Are there any errors in the browser console?


Hi Tommy,
no errors are displayed in browser console.
I can see the
console.log(“SUCCESS INIT”);
in browser console, but nothing happens.
